ROVING-CREEL ron srrnnrne AND DOUBLING FRAMES.

Specification of Letters Patent.

Patented oeaae, 1915.

Application filed February'l i, 1914. Serial No. 818,640.

Our invention relates to metallic roving creels, and consists in a novel sheet-metal formation of the middle creel-boards thereof adapting the same to resist objectionable vibration when the frame is in operation and,

providing a rigid, durable and cleanly support for the roving bobbins and their mountings, of comparatively thin metal and at low cost.

The invention also includes the construction and disposition of the step journals and top holders for the skewers of the roving bobbins, wherebythey are concealed from View and protected from injury, as will be hereinafter explained and more particularly pointed out in the appended claims.

In the drawings forming a part hereof,

Figure 1 represents, in vertical transverse section, a metallic roving creel of a spinning frame having a middle creel-board embodying our invention and illustrating the use thereof; Fig. 2 is a plan view section of the said middle creel board on an enlarged scale; and Fig. 3 is a transverse section of Fig. 2 on line III-HT thereof.

The creel shown in Fig. 1 comprises a bottom-board 1 of pressed sheet metal, which is mounted on the cross-braces 2, joining the roller-beams of the frame, and the said bot tom board forms the support for the uprights 3 upon which are mounted the vertically adjustable brackets a which carry the two upper creel-boards.

The reference numeral 5 designates roving bobbins carried as usual by their skewers 6, which are held in upright positions in the spaces or storiesbetween the creel-boards so that the yarn therefrom, as indicated by the dotted lines, may pass over the yarn-guide and from thence through the drawing rollers to the spindles, in the usual and well understood manner.

The middle creel-board comprises upper and lower sheet-metal plates 8 and 9, co-eX- tensive with the length of the creel and united together along longitudinal lines in parallel relation to each other, and with an open space between them. The skewer-step ournals 10 and the top holders 11 for the skewers are held in perforations in these plates and project inwardly into the space between them, whereby they are inclosed and concealed from view, and whereby the creel-boardpresents smooth upperand lower surfaces, which. are devoid of projections likely to catch oil or dirt, or obstruct the cleaning brush. As. shown more clearly in Figs. 2 and 3, the said middle creel-board is preferably formed of two parallel and similar members, each formed from a sheet-metal blank folded into hollow cross-section and constituting a half of the whole board. The two members are disposed in the same plane and united along their adjacent edges. The preferred formation of the blank consists in folding ittwice along itswapproximate longitudinal center, forming the right-angle corners 12, and the intermediate strip 12 which closesthe sides of the interior open space, and thereby producing a neat and rigid outer margin for the board. The free or inward margin of the upper plate is bent downwardly at right angles, as shown at 13, further stiffening the construction and producing a rectangular cross-sectional shape for each hollow member. The two members are united by bolts or rivets passed through their adjacent or contiguous flanges 13, for which purpose hand holes are cut out of the edges in the lower plate 9, as indicated in the drawings. The vertical sides 12 and the united central flanges 13 form continuous longitudinal connections between the two plates and serve as stiffening means therefor which particularly serves to prevent or dampen objectionable vibration from taking place in the board between its supports. The skewer-steps 10 rest in perforations in the upper plate, being held in position therein by their head flanges, as indicated, or other suitable means, so that their lower ends occupy the hollow interior of the member. The top-holders for the skewers are flanged thimbles with cylindrical or slightly tapered barrels which are pressed upwardly from below through the perforations in the lower plate 9 until their flanges meet the creel-plate and the upper parts of their barrels occupy the interior space within the member, in which position they are retained by friction. v The outwardly turned flanges on the thimbles serve to maintain the barrels in strictly upright position Within the member and provide a smooth flaring entrance and bearing for the top of the skewer, withoutmaterially wearing the latter.-

It will be understood that while the invention as herein shown comprises but two members-united to form the complete middle-board, any desired number of members may be similarly employed for the same pur osen avingdescribed our invention, what we claim and desire to secure by United States LettersPatent, is':

1. In a roving creel, a hollow creel-board formed of sheetmetal with perforations in the upper and lower plates thereof, and having skewer steps and top holders respectively contained in perforations in said plates and projecting into the space between the same.

2. In a roving creel, a middle creel-board formed of upper and lower sheet-metal plates Vertically spaced apart in parallel relation and united along their margins and center line, incombination with skewer steps seated in perforations in said upper plates and top holder thimbles concentrically disposed with respect to perforations in the lower plate.

3. In a roving creel, a middle creel-board comprised of folded sheet-metal blanks of hollow rectangular cross-section and having parallel upper and lower plates, in combination with flanged skewer steps seated in perforations in the top plate and top holders concentrically disposed with respect to perforations in the said lower plates.

4;. In a creel, a middle creel-board comprised of upper and lower sheet-metal plates spaced apart in parallelism and united along longitudinal lines, in combination with skewer steps supported on said upper plate and flanged thimbles supported on said lower plate and forming top holders for the skewers.

5. In a creel, a middle creel-board comprised of upper and lower sheet-metal plates co-extensive with the length of the creel, and spaced apart in parallelism, said members being united along their adjacent edges, in combination with flanged thimbles secured to said lower plate with the barrels thereof projecting into the space between said plates.

In testimony whereof, we have signed this specification in the presence of two witnesses.
